Cervélo S5 Red AXS Road Bike 2025
The Cervélo S5, engineered for speed, has proven its superiority under top cyclists like Wout van Aert, Marianne Vos, and Christophe LaPorte. In the 2022 Tour de France, Wout achieved a record-breaking Points Classification score of 480, outpacing his nearest rival by 194 points. This highlights the S5's exceptional performance. The new model reduces drag by 65 grams, increases frame surface area, and lowers overall weight. With deeper frame sections optimized within UCI regulations, a refined V-stem, and a redesigned fork for a streamlined front end, the S5 excels. Moreover, a cutting-edge wheel design co-developed with Reserve enhances stability and reduces drag in turbulent conditions.
